Enable Basic WildFire Forwarding
WildFire is a cloud-based virtual environment that analyzes and executes unknown samples (files and email links) and determines the samples to be malicious, grayware, or benign. With WildFire enabled, a Palo Alto Networks firewall can forward unknown samples to WildFire for analysis. For newly-discovered malware, WildFire generates a signature to detect the malware and distributes it to all firewalls with active WildFire licenses. This enables global firewalls to detect and prevent malware found by a single firewall.
A basic WildFire service is included as part of the Palo Alto Networks next generation firewall and does not require a WildFire subscription. With the basic WildFire service, you can enable the firewall to forward portable executable (PE) files. Additionally, if do not have a WildFire subscription, but you do have a Threat Prevention subscription, you can receive signatures for malware WildFire identifies every 24- 48 hours (as part of the antivirus updates).
Beyond the basic WildFire service, a WildFire subscription is required for the firewall to:
- Get the latest WildFire signatures every five minutes.
- Forward advanced file types and email links for analysis.
- Use the WildFire API.
- Use a WF-500 appliance to host a WildFire private cloud or a WildFire hybrid cloud.
If you have a WildFire subscription, go ahead and get started with WildFire to get the most out of your subscription. Otherwise, take the following steps to enable basic WildFire forwarding:
- Confirm that your firewall is registered and that you have a valid support account as well as any subscriptions you require.
- Configure WildFire forwarding settings.
- Selectand edit the General Settings.DeviceSetupWildFire
